PURPOSE: To demonstrate the parabolic path of a projectile.

DESCRIPTION: A water stream is projected in front of a cartesian coordinate grid that can be shadow projected using a bright point source (not photographed). If desired, coordinates of the water stream can be read. The reservoir is a bottle which provides constant water pressure even as the water level drops in the container.
